Hugely disappointed with it. Firstly, this is a toy released that is based on the the technology you saw in the video which is a $30,000 product.
It's simply a retail version which doesn't dance to the music for more than a few seconds and needs to pause every 7-8 seconds to re-listen.
The touchy feely side of it is quite entertaining as a little companion for kids or your desk, but it sleeps after a short period and has cycles to run through constantly.
Oh and it can sometimes get stuck in a cycle which will require you to reset it.
I emailed the manufacturer about my concerns and they said it is what it is, it's not the one you've seen and that's about all it does.
